Wave is a technology family, not one ride
Mizuno uses the Wave name across multiple constructions and shoe categories. Seeing Wave in a title does not establish that a shoe is a stability trainer, nor that it contains the same component as another Mizuno model. This matters when you compare an older favorite with a new release.
Start with the intended role of the exact model. Inspire and Horizon are support-oriented families worth considering, but technical descriptions should remain attached to their generation numbers. A review of an old Inspire should not become a promise about the fit, foam or transition of its successor.
Use Inspire and Horizon as different fitting questions
With Inspire, ask whether the everyday training package feels comfortable at the pace you normally run. With Horizon, ask whether its more substantial cushioning approach provides an experience you prefer. Avoid turning those questions into an automatic ranking of runner ability or body size.
Mizuno’s Wave Horizon 9 product information describes Foam Wave as a layered foam construction. That is a useful counterexample to the assumption that every supported Mizuno must rely on the same traditional plate. Manufacturer terminology explains intended design; it cannot tell you exactly how the shoe will feel under your own foot.
Check heel-to-forefoot continuity
A shoe can feel comfortable beneath the heel yet less appealing as you move toward toe-off. During a fitting, concentrate on the whole transition rather than the landing alone. Notice whether the forefoot bends or rolls in a way that suits your normal pace and whether the midfoot draws unwanted attention.
Use complete pairs and repeat the same short route for each. Wearing different models on opposite feet may highlight differences, but it is a poor final decision method when your feet are not identical. Include a relaxed turn and some walking if the shoe will also serve everyday use.
Compare with your actual previous shoe
If replacing a Mizuno you enjoyed, record its full name and generation before shopping. Tell the fitter what worked: secure rearfoot fit, a particular cushioning sensation or the shape of the arch area. Being specific helps identify whether the new edition preserves the relevant characteristic.
Check width availability in your region and inspect the exact product listing before ordering. If Inspire and Horizon both fail on the same fit detail, expand the search beyond Mizuno rather than assuming a third size will necessarily solve it. Brand familiarity is convenient, but it is less valuable than a shoe that fits your current needs.

Does Wave always mean a plastic plate?
No. Mizuno uses different Wave constructions, including Foam Wave. Check the precise model’s official specifications.
Should I choose Horizon because it sounds more supportive?
Only if its fit and ride suit your purpose. A family’s positioning is a reason to try it, not evidence that it will outperform another shoe for you.
